Brief summary (from the registry)
Chronic pain is a debilitating condition affecting 1 in 5 Canadians with a yearly economic cost of over $40 billion in healthcare spending and loss of productivity. Since the prevalence of chronic pain is increasing, especially as the population ages, effective low-cost treatment is key to reduce the impact of chronic pain on patient quality of life and on healthcare costs. Due to the complexity of chronic pain and differences between the multitudes of pain conditions, developing effective treatments is challenging. This is especially true for Complex Regional Pain Syndrome (CRPS). CRPS is characterized by severe pain out of proportion to tissue trauma, with local autonomic and inflammatory changes. The severity of pain from CRPS may result in an inability to work, depression, sleep disorders, or suicidal ideation. Although its prevalence is low in Canada, CRPS is considered one the most debilitating and least understood pain conditions. As most current treatment options have low evidence of effectiveness, there is no definitive treatment available and most often, patients are struggling to maintain an acceptable quality of life. Thus, there is a pressing need to identify new and improved treatments for adults with CRPS. An early hypothesis of CRPS pathophysiology posited that sympathetic nervous system over-activity led to many of the signs and symptoms of CRPS. As such, sympathetic nerve blocks, including stellate ganglion and lumbar sympathetic blocks, have been repeatedly investigated as a potential treatment of CRPS. However, a recent meta-analysis suggests that these blocks provided no benefits for those suffering with CRPS. Newer evidence suggests that a peripheral microvascular dysfunction may underlie CRPS pathophysiology. However, no clinical trials have investigated the efficacy of a treatment targeting this peripheral pathway. The goal of this project is to assess the efficacy of a single-shot axillary approach to the brachial plexus block plus physiothe…
